Tilt down state.

The wiring host 16 of the present invention is a prior art, and will not be repeated here.

The working principle of the utility model is:

Facing the input shaft 10, when the input shaft 10 rotates counterclockwise, the balance frame A11, the fixed rod 14, and the balance frame B12 that belong to a whole are inclined with the rotation of the input shaft 10; due to the effect of the fixed rod 14 (with Upper and lower rollers 18,19 contact), the cable main frame 16 also tilts. In the process of tilting, the tentacles 17 on the gimbal B12 gradually approach the plane of the lateral side of the L-shaped bracket 4 . At the same time, the prong angle A501 and the prong angle B502 of the shift fork 5 are inclined towards the direction close to the lead screw A2, and the prong angle C503 and the prong angle D504 on the other side are inclined in the opposite direction (tilted upward). When the tentacles 17 were in contact with the plane of the support 4, the cable host 16 and the balance frame A11 connected thereto, the balance frame B12, and the fixed rod 14 no longer tilted; at this time, due to the rotation of the input shaft 10, the cable host 16 moved to The left side keeps moving, as the shift fork 5 is constantly approaching the block A3, because the shift fork 5 is inclined, the fork angle A501 of the shift fork 5 will contact the block A3, because the fork angle D504 is opposite to the fork angle A501 Upturned, the prong angle D504 will not contact with the stopper A3 (the same as the existing polished rod cable puller). Block A3 pushes shift fork 5 to the other side (torsion spring 6 assists shift fork 5 to rotate), thereby realizes reversing. When moving to the other end, the prong B502 on the shift fork 5 is in contact with the stopper B13, and the shift fork 5 is pushed back by the above operation stopper B13.

When the input shaft 10 rotates clockwise, the prong angle C503 and the prong angle D504 of the shift fork 5 are tilted towards the direction close to the lead screw B7, and the reciprocating movement of the cable host 16 can also be realized. It can be seen that no matter how the input shaft 10 rotates, it can realize The reciprocating movement of the cable main frame 16 makes the optical fiber be retracted evenly through the guide wheel 16 .
